New Command: build

[Cooldude2606]

The command should create a build dir and then inside it place whole collections ziped, and all submodules of collections ziped under the names Collection.Submodule. It should also create a set of json files which can be imported into the sql database with the correct urls within them. The command should require a base url as a param such as:
https://github.com/explosivegaming/scenario/releases/download/v4.0-core
Which will then be appended with the module name to become the upload location of the module eg: https://github.com/explosivegaming/scenario/releases/download/v4.0-core/ExpGamingCore.Commands.zip
The uploading of the zip files would need to be manale but the urls within each json will already be updated with the new url and the export jsons will be created to be added to the database.

Added (see commit) however it may be a good idea to also update the submodules atribute inside the collections with the new urls rather than just the the submodule jsons.
